SuperZipUse cases
Made for real life.
From a private vault for your photos to a treasure hunt where every team holds one key. Here is what people lock with SuperZip.
For you
Your private vault.
Photos, videos, ID and medical scans, tax papers, password lists and phone backups stay private. Create a free AES-256 ZIP or 7z file in a few taps. The originals stay untouched.
- Passport, bank and insurance copies for travel
- Backups you can store in any cloud
- Free for ZIP and 7z
For family
Keys held by the people you trust.
Give each relative one key. The package opens only when everyone brings theirs, in any order. Store the one file on three devices and it stays useful for years.
- Wills, property papers and emergency instructions
- Letters and photo albums with an opening date
- Pass-on copies when only some family members meet
For work
Deliver files only the right people can open.
Send a client file that opens with their key and yours. Add a second approver for anything important. Hidden file names keep the contents private even from someone who finds the package.
- Client deliveries and contracts
- Payroll and board papers with two approvers
- Handovers when a colleague leaves
- Designs and source files sent to a vendor
For schools and exams
Two keys. One hour. One paper.
Seal question papers so they open only when two invigilators enter their keys at the exam hour. Hold results until a set time. Share control between staff with no shared password.
- Question papers and answer keys
- Results released at a set time
- Shared control between staff
For professionals
Sensitive files, handled with care.
Lawyers, doctors, accountants, journalists and researchers share confidential files every day. SuperZip packages hide file names and use Argon2id key stretching for every password.
- Hidden file names
- Strong key stretching
- A copy that stays safe on a lost phone or in cloud storage
For fun and proof
Seal it today. Reveal it later.
Lock a message and share the file now. Open it together on the day. The public cover can carry the first clue for everyone to see.
- Time capsules and birthday surprises
- Escape rooms and treasure hunts where every team holds a key
- Sealed predictions that prove "I told you so"
- A peace offering sent to two people with one key each
